The utility model is as follows using technical solution:
A kind of multi-layer electret melt-blown non-woven material one-step method preparation facilities comprising rack and on the rack from upper
And melt-spraying spinning component, Corona charge component and the reception roll assembly of lower laying, the melt-spraying spinning component and the corona are stayed
Pole component is multiple and quantity is identical；The melt-spraying spinning component includes sequentially connected screw extruder, filter, metering
It pumps, spinning head, hot-air chamber is installed on the outside of the spinning head；The Corona charge component includes electrostatic generator, electricity
Dizzy electret needle plate and Corona charge needle, the electrostatic generator and Corona charge needle plate are electrically connected, the Corona charge needle peace
On Corona charge needle plate；It is described receive roll assembly include the reception lace curtaining that is rotated by rack-mounted motor driven and
It is mounted on the sucktion fan for receiving lace curtaining under or within.
Further, the exhaust air flue of the hot-air chamber is directed toward the spinneret orifice of the spinning head, the exhaust air flue
It is in 60 degree of angles between spinneret orifice.
Further, the vertical range of the spinneret orifice of the spinning head and reception lace curtaining upper surface is 10-20 centimetres.
Further, the Corona charge needle and the vertical range for receiving melt-blown non-woven material surface on lace curtaining are 2-5
Centimetre.
Further, the material of the Corona charge needle plate is silver or copper or gold or aluminium, the material of the Corona charge needle
For tungsten or cadmium or nickel or iron.
Further, the needle point density of Corona charge needle is 8100-16000 pieces/square metre on the Corona charge needle plate.
Compared with prior art, the utility model has the beneficial effects that: being stayed by multiple groups melt-spraying spinning component and corona
Pole component prepares multi-layer electret melt-blown non-woven material and stacks gradually molding on same reception roll assembly, realizes multilayer electret
The preparation of body melt-blown non-woven material one-step method, compared with traditional single layer preparation again MULTILAYER COMPOSITE, the equipment knot of the utility model
Structure is compact, occupied area is small, high production efficiency, production cost are low, stable product quality.
